SPECIFICATION forming part of Ltters Patent Nvo.eo8,5v4, dated August 9, 189s. Application tied Nimh 7, 189s. ,Seriana 673,979. `(No model.)

To all whom t may concern: y

Beit known that I, JOHN R. CARTER, a resident of Cincinnati, in the county ofHainilton and State of Ohio, have invented certain new and useful Improvements in Heating-Stoves; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in heating-stoves, the object being toprovide a stove having a central fuel-feed, with downdraft-tlnes communicating with buthlocated outside of the fuel-feed collar, so as not to interfere with the feed of fuel.

A further object is to provide a stove with a series of hot-air-blast flues located around a central fuel-opening, so as to distribute heated air over practically the entire bed of Aincandescent fuel, so as to insure uniform and practically complete combustion'of 'the' gases generated.

With these objects in view my'invention consists in the parts and combinations of parts, as will be more fully explained, and pointed out in the claims. y

In the accompanying drawings, Figure l is a view in vertical section,`partly in elevation,u of a stove embodying my invention; and Fig. 2 is a detached View, partly in transverse section.

A represents a stove of any approved form and designed for burning either wood or coal. Vhen used for burning coal, the stove should be provided with a movable grate, but'when used in a wood-burning stove, a closed fuelpot similar to that'disclosed in theJ ames application, Serial No. 645,254, led July 20,1897, should be used. I prefer, however, to provide the stove with a damper for supplying air at a point near the base of the tire-pot, and in coal-burnin g stoves this damper should be on a door conveniently located for the removal of ashes. In either instance, however, the stove is provided at a point centrally over the fire-pot with-an opening for the introduction of fuel, and within this opening and leading downwardly somedistance'below the 'free for the-admission of fuel.

top of the fire-spot is the collar B. This collar is cylindrical in shape and is provided at lower end with an inwardly-turned flange b,

forming a seat, on which rests the removable lid C, having a handle c.' This lid closes the top of the fire-pot and prevents, to a large extent, the entrance of air at this point. Secured to the collar and communicating with openings in the collar are the air-blast pipes D, which latter are located in vertical planes outside of the collar, and hence leave the whole interior of the collar free and clear for the introduction of fuel. These pipes extend well down into the fire-pot, so as to discharge the air directlyonto the burning fuel, and as thereare preferably a plurality of hot-blast Vpipes employed it will be seen that the air drawn` in is pretty well diffused over the entire body of burning fuel, thus mixing with the gases generated and promoting combustion, and as the pipes are subjected to the heat of the burning fuel the air is heated, and hence in proper condition for quick and thorough assimilation with the gases. The collarand fuel-opening may be covered with a register-plate or with a hood or cap having a damper therein.

In some stoves it might be desirable or advantageous to provide the stove with a fueldoor in front, Vand in such instance I would prefer to use three blast-pipes, one at each side and oneat the back, leaving the front When it is desired to introduce fuel through the top opening of the stove or through the collar, the register plate, cap, or hood, or other part employed for closing `the fuel-opening, and the lid'C are removed, thus permitting the free and ready introduction of fuel without removing or interfering in the least with the blast-tubes. When the lid and register plate or cap are in place, air entering the latter is deflected by the lid and passes down to the burning mass through the blast-pipes.

While I prefer-to employ av plurality of pipes7 still one might be considered suilieient. I'Ienee I do not @are to limit myself to any particular number.

It is evident that other changes might be made in the general form and arrangement of the several parts herein shown and deseribed Without departing from the spirit and scope of my invention, and lienee I Would have it understood that I do not limit myself to the preeise details herein set forth, but oonsider myself at liberty to make such changes and alterations as fairly fall within the spirit and seope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The Combination with a stove having a fuel-opening through its top, a removable hood for Closing said rFuel-opening and a eollar seated within said opening, of a draft-pipe Carried by said eollar and projecting downwardly into the ii1e-pot, a removable lid lo eated Within the eollar and below the draftopening therein and a damper above said draft-opening in the Collar.

2. The combination with a stove having a fuel-opening through its top, a removable hood for closing said fuel-opening and a eollar l1aving an outwardly-turned flange at its upper end and an inwardly-turned flange at its lower end, the upper ll ange of said collar resting on the top ofthe stove, of a draft-flue outside the collar but secured to and depending from the same, a removable lid seated on the lower flan ge of the eollar and a damper-plate elosing the upper end ot the eollar.

In testimony whereof l have signed this specification in the presence of twosubseribing Witnesses.
